ABSTRACT:
High and low frequency components Cn1, Cn2are generated by causing a center channel audio signal Cn to pass through a high-pass filter HPF and a low-pass filter LPF, and the high frequency component Cn1is supplied to the center channel loudspeaker SPC. Also, two low frequency components Cn2L, Cn2R, which have a different phase mutually, are generated by causing the low frequency component Cn2to pass through phase shifters2, 3. An synthesized audio signal SL is generated by synthesizing the low frequency component Cn2Land the front-left channel audio signal FL, and then supplied to the front-left channel loudspeaker SPL. An synthesized audio signal SR is generated by synthesizing the low frequency component Cn2Rand the front-right channel audio signal FR, and is supplied to the front-right channel loudspeaker SPR.
